HUMIDIFYING AIR U -Sewell Munson Corbett,,Fort Bragg, N. C. 1 Application April 18,1929. Serial No; 356,197 7 3 Claims. (01. 237- 78)-.-

I (Granted under the act of March. 3, 1883,"as

amended April 30, 1928; 370 0. G. 757-) This invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

Ithas been found'that, by suitably humidifying the atmosphere in compartments, the atmosphere is rendered more sanitary and the occupants are kept comfortably warm at lower temperatures than is possible where humidification is not employed. It is the general object of my invention to provide a system .or apparatus whereby the humidification of the atmosphere in such compartments may be conveniently, effectively, and automatically secured and controlled. 7

In carrying out my invention, I provide a vaporizer which is subjected to the action of heat (as by locating the same in close relation to a radiator) and control the supply of water to such vaporizer in accordance with temperature conditions within the radiator. For the purpose of so controlling the supply of water to the vaporizer, I prefer to use a thermostat which is subjected to the temperature of the radiator and which, in the present preferred embodiment of my invention, is located within the radiator.

In the drawing forming part hereof, there are shown three embodiments of my invention, Fig. 1 showing a side elevation of the vaporizer, a pipe for supplying liquid thereto, and a thermostat controlling the flow of. liquid through said pipe, the radiator being shown in broken lines; Fig. 2 an enlarged detail insection through the thermostat and the portion of the radiator in which the same is located and through the casing of the valve which is controlled by said thermostat;

' Fig. 3 a detail in elevation ofthe vaporizer shown in Fig. 1; Fig. 4 a detail in elevation of a modification of my invention; and Fig. 5 a view, similar to Fig. 1, showing a still further modification of my invention.

Describing the various parts by reference characters, and'first in connection with Figs. 1 .to 3 inclusive, 1 represents a radiator which may be of any ordinary, standard construction, but having nearthe top of one of the end loops an opening 2 through which the casing 3 of a thermostat is inserted. This casing is of sufiiciently small diameter to not materially obstruct the circulation of the heating fluid through the end loop 1 and through the opening 1 into the adjacent loop. The casing is provided with a transverse plunger 4 between which and one of the end walls 3 of said casing there is provided a chamber 5 for the reception of liquid having a relatively high coeilicient of expansion. Con

'casing 3 outside of but in close proximity to the nected with the center of the plunger 4 is a stem 6 which extends through the outer end of the casing 3 and through the adjacent sidewall of a valve casing "7. The stem 6'is provided within such valve casing with a tapered valve 8 cooperating with a correspondingly shaped valve seat 9 in a partition 9. g I

10 denotes a pipe through which the water to be vaporized is delivered into the casing 7 at one side of the partition 9, and 11 denotes a pipe leading from said casing and from the other side of said partition to a vaporizing nozzle 12, which is located in close proximity to the radiator; The nozzle is preferably of the fan shapeshown herein and'is provided in its upper extended surface with a large number of fine openings 12 through which water vapor is discharged into the room or compartment.

With the parts constructed and arranged as described in Figs. 1-3 inclusive, the operation will be readily understood. Unless and until the fluid in the radiator shall have reached a predetermined temperature, there will be no flow of water to the vaporizer. However, when this temperature shall have been reached, the expansion of the liquid in the chamber 5 will move the piston 4 toward the right, thereby openingthe valve 8 a corresponding extent and permitting a corresponding flow of water into the pipe 11 and to the vaporizer 12. By limiting the opening of the valve I in this manner, the water will not be delivered to the vaporizer until the latter is heated to a sufiicient extent to enable the water supplied thereto to be vaporized and discharged into the room. It will be evident that, the higher the temperature of the fluid in the radiator, the more rapid will be the delivery of water to the vaporizer and the more rapid will be the evolution of vapor in the vaporizer and the delivery of such vapor to the room or compartment in which the radiator is located. Furthermore, when the temperature of the liquid in the radiator falls, the liquid in the chamber-5 contracts, and a spring 13, which is interposed between the piston 4 and the outer end of the casing 3, will move the piston'to the left, thereby moving the valve 8 toward its seat and correspondingly cutting down the flow of water to the vaporizer; when the temperature within the radiator falls to a'predetermined point,

the valve -8 will be entirely closed and no more 105 'water will be'delivered to the vaporizer.

In Fig. 4 there is shown a modification of my invention which differs from that illustrated in the preceding views in placing the thermostat o 2 radiator. ft wi ll be understood that the thermostat will be identical in construction with that shown in the preceding views; also that the valve and valve casing will be constructed in the same stead of using a special vaporizing nozzle, the pipe 11 delivers the water to a length of pipe 14 which is provided with a plurality of fine perforations (not shown) which will discharge the water upon one or more sheets of absorbent material 15, suspended from the said pipe 14. The absorbent material may be cloth or felt, and is located in close proximity to the radiator in order to facilitate the vaporization of the water delivered thereto.

Havingthus described my invention, what I claim is:

1. The combination, with a fluid-containing radiator, of a vaporizer located in proximity to said radiator, a conduit leading to said vaporizer, a thermostat in said radiator whereby it is exposed to the temperature of the fluid circulating therethrough, a valve in said conduit, and an operative connection between the said valve and the said thermostat.

2. The combination, with a fluid-containing radiator, of a vaporizer, a conduit leading to said vaporizer, a thermostat in said radiator whereby it is exposed to the temperature of the fluid circul'ating therethrough, a valve in said conduit, and an operative connection between the said valve and the said thermostat.

3. The combination, with a fluid-containing radiator, of a vaporizer arranged in proximity to said radiator, a conduit for delivering liquid to said vaporizer, a thermostat in said radiator, a valve in said conduit, and connections between said thermostat and said valve whereby liquid will'be delivered to said vaporizer in accordance with the temperature of the fluid within the Ta diator.
